Embodiment 1
[0269] Based on the simulation parameters in Table 1, this embodiment simulates the data-centered communication method in the present invention, and the performance analysis is as follows: when the node obtains data from the local subnet, the data communication delay and cost are relatively small, and when the node obtains data from the remote subnet When the network accesses the network, the data communication delay and cost are relatively large. When a node obtains data from the local subnet, the average delay in obtaining service data is 40ms, and the average cost is 7. When a node obtains the network from a remote subnet, the average delay in obtaining service data is 70ms, and the average cost is 12.

The invention provides a data-centered communication method. The network includes an IPv6 backbone network, a data-centered subnet and an IP subnet, and the data-centered subnet is called a data subnet. The IP subnet includes access routers, IP common equipment, IP data providers and IP data consumers; the IP subnet is connected to the IPv6 backbone network through the access router; in the IP subnet, the IP data provider is able to generate or provide A data server or node that supports the IP protocol; an IP data consumer is a node that is authorized to obtain a type of data and supports the IP protocol; an IP common device is neither a data consumer nor a data provider, and is used to perform routing and forwarding functions , support IP protocol; nodes can obtain service data from the nearest node in unicast mode, which shortens the delay and cost of obtaining service data and improves service quality. The present invention can be applied to large data acquisition and other fields, and has a wide range of applications prospect.
Description
technical field [0001] The invention relates to an implementation method, in particular to a data-centered communication method. Background technique [0002] The network has become an indispensable part of human life, it provides a variety of data services, so reducing data communication delay is particularly important. In recent years, a lot of research work is dedicated to the data communication of the network, so that people can quickly obtain network services. With the development of network technology, the data communication technology of the network will further improve the service quality. [0003] At present, the delay and cost of data communication in the network are relatively large, which reduces the performance of network services. Therefore, how to reduce the delay and cost of network data communication has become a hot research issue in recent years. Contents of the invention [0004] Purpose of the invention: The technical problem to be solved by the pre...
